w/Amendment 1
4.5.2.1.6 Noncompliance. If a sample fails to pass group B inspection, the supplier shall take corrective action on
the materials or processes, or both, as warranted, and on all units of product that can be corrected, and that were
manufactured under essentially the same conditions, with essentially the same materials, processes, etc., and which
are considered subject to the same failure. Acceptance of the product shall be discontinued until corrective action,
acceptable to the Government, has been taken. After the corrective action has been taken, group B inspection shall
be repeated on additional sample units (all inspection, or the inspection that the original sample failed, at the option
of the Government). Group A inspection may be re-instituted; however, final acceptance shall be withheld until the
group B re-inspection has shown that the corrective action was successful. In the event of failure after re-inspection,
information concerning the failure and corrective action taken shall be furnished to the cognizant inspection activity
and the qualifying activity.

If the failures exceed the total number permitted by 1, the inspection shall be rerun with the same sample size
with zero failures permitted.
4.6 Methods of examination and test.
